Optimize conditional branch on i1 phis with non-constant inputs.
This turns:
eq:
%3 = icmp eq i32 %1, %2
br label %join
ne:
%4 = icmp ne i32 %1, %2
br label %join
join:
%5 = phi i1 [%3, %eq], [%4, %ne]
br i1 %5, label %yes, label %no
=>
eq:
%3 = icmp eq i32 %1, %2
br i1 %3, label %yes, label %no
ne:
%4 = icmp ne i32 %1, %2
br i1 %4, label %yes, label %no
